Abstract

Stringent control of Mn is critical for drinking water safety. However, conventional rapid sand filters exhibit slow biological maturation for Mn(II) removal, limiting their performance in engineered Mn(II) removal. This study examined the effectiveness of partially replacing sand with natural manganese ore (NMO) to enhance Mn(II) removal and elucidated the underlying mechanisms. The results showed that replacing only 1/8 of sand with NMO enabled consistently effective Mn(II) removal (residual
